@Xulfiqar bhai, the car is 2003 2.0D saloon, used to jump another car this morning. tonight about two hours ago, I tried to start it and twisted the key to on positio there were relay clicking like sounds from glovebox (probably where interior fuse box is), optitron meter, audio system and all lights except airbag light went out. It didn't start and self starter fainted after trying 3 times, heater light came on for 2 times but off instantaneously then didn't come on again. the only electric accessory working are headlights (not parking lamps even).
What could be the cause?
I believe karma is hitting me as I planned to take out a fuse or two to avoid reaching a family gathering a few days ago but didn't touch anything only not even the fuse box cover.
